REFRIGERATOR.

SPECIFICATION forming part of Letters Patent No. 498,612, dated May 30,1893,

Application filed April 2l, 1892. Serial No. 430.064. (No model.)

To all whom it may concern,.-

Beit known that I, HENRY C. BEARDSLEY, a citizen of the United States,residing at New Duluth, in the county of St. Louis and State ofMinnesota, have invented certain new and useful Improvements ,inRefrigerators, which are fully set forth in the following specitcation,reference being had to the accompanying drawings, in which- Figure lrepresents an edge View of the drain pipe and trap embodying myinvention with a portion of the refrigerator in section; Fig. 2, asection of the same, taken on the line 2-2, of Fig. 1 Fig. 3, a sideelevation of the trap, detached; Fig. 4, a plan of the same; and Fig. 5,an elevation of an upper or inlet pipe made of glass for the trap.

My invention relates to traps for refrigerators and consists in certainspecial features of construction, which I will proceed to describe indetail and will rthen point out more definitely in claims the specificimprovements which I believe to be new and wish to secure by LettersPatent.

It is very important to keep the interior of refrigerators as dry aspossible and so it is desirable to drainV off the water therefromconstantly, so as to prevent any accumulation. At the saine time it isabsolutely necessary to prevent the entrance of air from the outside andso a trap, or some other device becomes important for the drain outlet.

In the drawings, A represents a refrigerator, and, a., the bottom of theice chamber, a',

the back of the refrigerator, and, a2, the bottom thereof. Water will beformed in the ice chamber, of course, by the gradual melting of the iceand this water ought to be drawn off at once. To this end,a drain pipeor conduit is provided entering through the bottom of the ice chamberabout midway of the refrigerator and extending down through the latterand the bottom thereof to discharge the drip water outside. This drainpipe, as shown in the drawings, is composed of two sections, an upperone, B, and a lower one, C, and between the two is a trap, D. The uppersection B of the drain pipe is inserted in the bottom of the icechamber, so as to take the drip directly therefrom and extends a littleway below this bottom of the refrigerator and at its lower end isinserted in the upper end ot' the trap. The drain pipe may be located atany other point, if desired.

The trap D is m'ade of glass, or rather the 55 `body is of glass, eastin one piece ofthe form shown in Fig. 3, with an outlet or neck, cl andd', at the respective ends, these outlet necks being set out of linewith each other, as seen in Figs. 2 and 3. Each of the necks d, d iscast 6o With an external thread, which is to provide for the applicationof metal caps E and F respectively to. said necks, the caps beingthreaded properly to be applied thereto. The caps are provided withcentral perforations e 6 5 and f. The cap E is applied to the upper endof the trap, a rubber gasket, G, being placed on the upper end of theneck d and the cap screwed down tightly upon the gasket, the latterbeing somewhat Wider than the thick- 7o ness of the glass, so as toextendl in beyond the same, as seen in Figs. 2 and 4. The cap F issomewhat deeper than the cap E to provide for the application of a shortglass pipe or tube, H, which is inserted in the bottom neckl of the trapand is provided with a circumferential flange or collar, h, adapted toiit against the lower neck of the trap when inserted in the latter. Thecap F is then screwed upon the neck d', a rubber gasket, 8o I, beingplaced between it and the collar on the pipe H, so as to make atightjoint and firmly secure the pipe in the trap. This pipe H passesthrough the central opening in the cap F and extends a little below thesaine and enters the upper end of the section O of the drain pipe, asseen in Fig. 2, the latter being thence extended downward to and throughthe bottom of the refrigerator. v The upper section B of the drain pipeis inserted 9o in the upper neck dof the trap, and, of course, must beextended down a little below the upper end of the tube H, so as toprovidea complete water trap. The inner edge of the rubber gasket G hugsthis pipe tightly and so provides a tight joint at this point ofconnection. The drip water fills the trap body B, or

it may otherwise be filled with water to the top of the outlet H, when,of course, the lower end of the pipe B will be covered and Ic'o so acomplete water trap provided for the drain pipe, so that the drip watermay be conveyed away immediately, as it is formed and at the same timethe entrance of air is prevented.

As the trap is of glass the interior is readily seen and so it may beinspected at any time to determine its condition. It will be noticedalso that the parts are all readily disconnected for cleaning, repairs,or any other purpose, but the trap may also be made with the partsnon-detachable, if desired. The trap may be' removed bodily by simplyslipping it upon the upper pipe B until disconnected from the lowerpipe, as seen in dotted lilies in Fig. 2, when it may be turned aroundout of the way of the lower pipe C, then slipped down and oft from theupper pipe.

As a modification of the construction just described,the trap may beprovided with a glass pipe or tube at eachend. For this purpose Iprovide a short glass tube or pipe, J, similar to the tube H, beingprovided with a like collanj. In this construction this tube J isinserted and secured in the upper end or neck of the trap body, the sameas already described for the tube H and in this modification the Lippermetallic pipe B is shortened and is connected at its lower end to theupper end oi" the glass tube J, instead of ruiming directly into thetrap.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

l, In a refrigerator an upper drip-pipe leading from the ice receptacle,in combination with a separate lower pipe C leading out from therefrigerator, and an independent cast glass trap, adapted to connect thesaid pipes and detachable at will therefrom Without removing either ofthe`pipes, substantially as described.

2. In a refrigerator, the trap D cast in glass and provided with thethreaded necks d, d', in combination with the perforated screw caps Eand F, the glass tube H secured in the lower neck ot' the trap by thecap F, the rubber gasket G secured on the upper neck by the cap E, andthe drip pipe fitting closely said gasket, substantially as described.

3. In a refrigerator, the glass trap D provided with threaded necks d,d,in combination with the screw caps E and F, the wide rubber gasket G,the drip pipe B closely itting said gasket, the glass tube H providedwith [iange h, whereby it is secured in the neck d by the cap F, and thelower or outlet pipe C fitting upon the projecting,r end of the tube H,substantially as described.
